Question

What is the mole to mole ratio of LiOH to HBr for the following reaction?

LiOH + HBr --> LiBr + H2O

How many moles are in 10.00g HBr?

Answer 1

Step-by-step explanation:

so moles = mass ÷ mr (1+ 79.9)

so 10.00g ÷ 80.9

which is 0.1236093943

so to 3 S.F is 0.124 moles

also there is 1 to 1 ratio for LiOH to HBr

hope this helps :)
